"We had Attic Masters remove and re install our old ducting. The ductwork in our house was the original ductwork that came with the house when we originally bought it 20 years ago so you can imagine how old and dingy they were. Attic Masters took care of out ducts within half a days work. Results increased air flow and Less noise."

Insulation is designed to maintain a stable interior temperature regardless of the outdoor weather. There are four main categories for insulation. The type you choose depends on these factors:
Fiberglass batts are the most common and least expensive way to insulate your home. They are installed during construction and renovations before the walls or floors are closed in. Properly installed, it improves the energy efficiency of your home by 25 to 30 percent.
Blown-In InsulationBlown-in insulation is made from white cellulose, a byproduct of recycled cardboard, newspapers and other paper materials. It provides excellent R-value which increases depending on the depth.
Spray Foam InsulationSpray foam insulation is ideal for filling tight gaps and spaces that make a home drafty. It begins as liquid polyurethane that is sprayed into an opening or cavity. It expands to fills the space and then hardens into solid foam.
Reflective or Radiant BarrierReflective or radiant barriers work the opposite way as do other insulation materials but it has similar results. Most insulation slows down the flow of heat, but the thermodynamics of radiant barriers causes it to reflect the heat and cold. It is commonly used in attics to minimize the effects of scathing summers or frigid winters.
The cost to purchase and install insulation varies regionally. The national average cost varies by material, with blown-in at around $880, fiberglass around $960 and spray foam around $1,100.
